Example: Enabling Remote Loopback Support on the Local Interface
You can allow a remote entity to set a local interface into remote loopback mode on
all Ethernet interfaces on the E Series routers in which OAM link-fault management
support is present. When a remote-loopback request is sent by a remote entity, the
JUNOSe Software places the local interface into loopback mode. When an interface
is in loopback mode, all frames except OAM PDUs are looped back without any
changes to the frames. OAM PDUs continue to be sent to the management plane
and processed. By default, the remote loopback feature is not enabled.
The following example configures the Gigabit Ethernet interface for OAM link-fault
management and enables it to be placed in remote loopback mode to respond to
loopback requests from the peer.
host1(config)# interface gigabitEthernet 4/1
host1(config-if)# ethernet oam lfm
host1(config-if)# ethernet oam lfm remote-loopback supported

Monitoring OAM Link-Fault Management Discovery Settings for an Interface
Purpose
Display the results of the Ethernet OAM link-fault management discovery process
for a particular interface, such as the hardware status of the interface, operational
status of the interface, status of the established link discovery mode of the local and
remote OAM entities, states of the multiplier and parser functions of the OAM sublayer
for the local and remote OAM entities, and functionalities and configuration of the
local and remote OAM entities.
Action
To display information regarding the OAM discovery process for a specific interface:
host1# show ethernet oam lfm discovery GigabitEthernet 4/1
GigabitEthernet 4/1 is Up, Administrative status is Up
OAM status is Down
Local(0090.1A03.0063):
Mode : active
Capabilities : link events
Mux Action : Forwarding
Parser Action : Forwarding
Remote(0090.690a.0202):
Mode : passive
